IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic analog of human IGF-1 with an extended half-life, allowing for prolonged activity in research settings. IGF-1 plays a critical role in cell growth, repair, and regeneration. Research suggests IGF-1 LR3 may support muscle hypertrophy, recovery, fat metabolism, and improved performance, making it a key compound of interest in studies on growth and longevity.
Black Pearl Labs provides IGF-1 LR3 in research-grade purity for laboratory use only. Not for human consumption.
